Abstract

A method and device for simulating a P2 hybrid vehicle engine test provided by the embodiments of the present invention relate to the technical field of hybrid transmissions and are applied to a bench control network, where the bench control network includes a bench controller, a hybrid control unit, and a simulation a motor; the method includes: the bench controller obtains the torque range of the engine to be tested according to the ignition control curve of the engine to be tested; the hybrid control unit determines the target torque based on the working condition information, and controls the simulated motor to enter the torque control mode; If the target torque is within the torque range of the engine to be tested, simulating the motor to execute the target torque, and simulating the hybrid engine for bench test, the hybrid control function can be realized, and the parameter adjustment is more convenient, and the cost and risk are low. Effect.

Description

technical field [0001] The present invention relates to the technical field of hybrid transmissions, and in particular, to a method and device for simulating an engine test of a P2 hybrid vehicle. Background technique [0002] Hybrid transmission is an important direction of transmission development, and bench testing is an indispensable part of the transmission development process. At present, traditional transmissions are generally set up as three-motor benches. figure 1 , in the figure 110 is the input motor, representing the engine, 120 is the transmission, 130 and 140 are two output motors, respectively, representing the left front wheel and the right front wheel of the car. The input motor simulates the output power of the engine, and the two output motors simulate the load at the wheel end. This kind of bench can not only carry out tests such as loading and efficiency, but also simulate the working state of the whole vehicle for dynamic shifting. In the dynamic shif...
